Celtic target Stephen O'Donnell has rejected a new contract at Kilmarnock.

The right-back became a mainstay in the Killie side under previous boss Steve Clarke before Angelo Alessio took over.

He played so well, in fact, that he earned his first nine international caps with Scotland.

Killie are understood to have stuck a new three-year deal on the table for the defender.

However just like last season, O'Donnell has knocked it back.

His current deal expires in the summer.

It has been previously reported that English clubs Derby County and Stoke City are also keen on the defender.
